3 Claims... (Cl. 222-146) This inventionrelatesto improvements :incir-;: culation equipment fororange juice dispensers... or fordispensers: for other beverages :including bottled water.

My invention is particularly directed to' improvements inbeveragedispensers having. means for keeping the beverage cool. Dispensers ofthis type are used for dispensing orange juice, either fresh juice ororange juice prepared by mixing frozen orange concentrate with water.;Orange;

juice usually contains some solid matter, such as some of the pulp ofthe fruit, and it is desirableto keep such juice in constantcirculation. Fur-.. thermore, dispensers which are in frequent. use:

require circulation of the beverage so that the juice dispensed will beuniformlycool.

It is an object of my invention. to provide an improved means which maybe readily built into present designs of cooling dispensers to-providefor circulationof the juice inthe containerfrom which the juice isdispensed.

It is further an object of my invention to provide circulation meanswhich will spray and aerate at least part of the juice circulated andthereby maintain the. pal atableness of 1. the beverage.

Further objects and advantages of myimprovements will be more readilyapparent from. the

following description of v preferred embodiments thereof as illustratedin-the accompanyingdrawr ings, in which:

Fig. 1 is a perspective View of the cooling. and dispensing equipment;

Fig. 2 is a horizontal cross-section of the apparatus shown in'Fig'; 1;

Fig. 3 is a vertical section taken on the plane indicated li-3 in Fig.2;

Fig. 4 is an enlarged view, partially in section, of the control valvefor the circulation of the fluid;

Fig. 5 is a vertical section similar to Fig. 3 but showing amodification; and

Fig. 6 is a schematic view of the electric wiring.

Figure 1 shows an exterior view of the cooling and dispensing system.The fluid dispensed may be water, orange juice, or any other beveragethat should. be cooled when dispensed. The housing It encloses themechanism. The spigot I2 is used for dispensing the liquid. The switch Il controls the pump for circulation of the liquid. The container !5 onthe top of the housing is preferably made of glass or other transparentmaterials, so that the liquid or juice contained therein is visible.

Referring to Figure 2, the cooling equipment may be of any suitabletype, including a compressor condenser unit 18 from which the.COI1'-T..densed. liquid. is :piped from the piper-20 .to zthei evaporatingcooling. coils: 22. The coils-22 :a'rezenclosed in "the housing. .24with suitable insulation:

. Fig. 3. The liquid maybelsprayedtasit is delivered from the upper endof the pipe 48 so as to cause some aeration of the liquid, the air beingreceived from the air pocket in the top of the bottle 34.

In addition to circulating the liquid, as described, through the upperend of the pipe 48, some of the liquid may be recirculated directly intothe container 30. I provide a nipple 50 extending from the pipe 48 intowhich extends a short tube 52 which is closed at its outer end 54 butwhich is provided with openings 56 adapted to cooperate with openings 58in the nipple 50 A packing gland 60 is provided to make a tight jointbetween the nipple 50 and the tube 52. It will be understood that byturning the tube 52 the amount of the liquid which is recirculateddirectly into the container 30 may be controlled and the flow increasedor decreased.

Figure 5 shows equipment which is generally similar to Fig. 3 but inplace of the bottle 34 I 3 have used a transparent liquid receiver 62which may be made of plastic. The receiver 62 is set into the rubberring 64 which also seals the top of the container 30. The cover 64 forthe receiver 62 fits loosely in place so that the liquid in the receiveris under atmospheric pressure. The equipment shown in Fig. 5 isprincipally used for display purposes. In this form, the vertical pipe18 delivers the liquid in a spray within a device 56 shaped to resemblean orange squeezer. From this device, the liquid is delivered throughthe spout B5. The device 66 may also be made of transparent plastic sothat, the customers may see the visible spraying and aeration of thejuice or other liquid being dispensed.

The wiring diagram shown in Fig. 6 illustrates the electricalconnections '10 to the compressor 5 I8 and the electrical circuit 72leading to the circulating pump 40. The switch it in the circuitlZ'controls the pump All. At night, when the dispensing equipment is notin use, the circulating pump may be cut off by opening the switch I4.Cooling and dispensing equipment as herein disclosed, may be used forbottled water in connection with water dispensers. In conventionalequipment the water in the bottle i not kept as cool as the water in thebottom which is near the cooling coils. Therefore, if a considerablequantity of water is drawn off, it will be found that, the water is notcold. With m equipment, the circulation of the Water tends t keep all ofthe Water close to the same temperature.

Another principal use of my cooling and dispensing equipment is for thedispensing of orange juice. The orange juice may be prepared from thefrozen concentrated juice to which water must be added. The circulationof the juice helps to mix the concentrated juice with the water when theequipment is first prepared for use. In addition, the orange juice hassome solid material which should be kept in suspension and thecirculation of the juice prevent the settling of the pulp or. othersolid matter. It is also important to provide for not only agitation ofthe juice but circulation to aerate the juice which tends to improve thetaste. On the other hand, too much aeration may be undesirable.Therefore, I provide for circulation by the pump and for delivering someof the juice directly into the liquid juice in the container withoutaeration while part of the juice is circulated and aerated by beingsprayed into the air to then fall back into the liquid juice.
